It is the most successful surgical operation in the 20th century and the most effective one. Every year, about 1 million patients get the ability to live near normal life through this operation.
7.What are the factors for the success of artificial total hip arthroplasty

Any surgical operation has certain risks, and artificial total hip replacement is no exception, but the percentage of risks is very low.
9.What are the possible complications of total hip arthroplasty?
The most serious complication is infection around the artificial joint prosthesis other major complications include: dislocation, deep vein thrombosis, pulmonary embolism, periprosthetic fracture, heterotopic ossification, unequal lower limb length, nerve and vascular injury, hip and thigh pain, periprosthetic bone resorption, osteolysis, prosthesis loosening, prosthetic stem fracture, prosthetic socket cup, ball head fragmentation, etc. The overall incidence of complications is about 1%.
10.How long can a successful total hip arthroplasty be used after the surgery?
Theoretically it can be used for life, but due to various reasons there are always some patients who have their prosthesis fail over time, currently most doctors believe that 90% of patients can use it for more than 15 to 20 years.
